Hi,
I have discovered a bug which causes our application to crash (boost lock
terminate).
We have an RTSP server with 2 subsessions (video+audio). If an RTSP client
requests to stream just one subsession (SETUP called only on 1 track) [video or
audio] the server will crash.
I have debugged the source code and fixed by altering the following:
In 'RTSPServer.cpp':
Within the 'handleCmd_PLAY' function the following checks
'fStreamStates[i].subsession != NULL' needs to be
'fStreamStates[i].streamToken!= NULL':
// Do any required seeking/scaling on each subsession, before starting
streaming.
// (However, we don't do this if the "PLAY" request was for just a single
subsession
// of a multiple-subsession stream; for such streams, seeking/scaling can be
done
// only with an aggregate "PLAY".)
for (i = 0; i < fNumStreamStates; ++i) {
if (subsession == NULL /* means: aggregated operation */ ||
fNumStreamStates == 1) {
if (fStreamStates[i].subsession != NULL) {
for (i = 0; i < fNumStreamStates; ++i) {
if (subsession == NULL /* means: aggregated operation */
|| subsession == fStreamStates[i].subsession) {
if (fStreamStates[i].subsession == NULL) continue;
// Now, start streaming:
for (i = 0; i < fNumStreamStates; ++i) {
if (subsession == NULL /* means: aggregated operation */
|| subsession == fStreamStates[i].subsession) {
unsigned short rtpSeqNum = 0;
unsigned rtpTimestamp = 0;
if (fStreamStates[i].subsession == NULL) continue;
N.B I have omitted line numbers as my source might not be the absolute latest.
